[Spice-devel] [PATCH v3 2/9] Avoid passing pipe item to red_channel_client_init_send_data()

The only time that the pipe item needs to be passed as the third
argument to red_channel_client_init_send_data() is when the pipe item
holds a data buffer that has been added to the marshaller by reference
(spice_marshaller_add_by_ref()) and needs to be kept alive until the
data has been sent. In all other cases, the item does not need to be
kept alive, so we can safely pass NULL for this third parameter.
